Had a Win 10 HDD crash. Had to reinstall Win 10 onto a new HDD. I want to merge the older ver 52.8 that resides on another HDD with the current installed ver 52.9 on the recreated Win 10 system. I had 5 email accounts in the "crashed" version HDD. Is this possible?

You can manually copy over data from one profile to another. http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Thunderbird
